A e cKe/ ATTORNEYS United States PatetitfO 2,727,660 snmr FOLDING MECHANISMS Application July 16, 1954, Serial No. 443,735 11 Claims. (Cl. 223-37 The invention relates to novel and improved shirt folding mechanism and more particularly to novel and improved means for holding the shirt cuffs while the shirt is being folded. The invention constitutes an improvement over that disclosed in my copending application, Serial Number 259,764, filed December 4, 1951, for Automatic Shirt Folder, now United States Letters Patent Number 2,665,039, granted January 5, 1954.

Said copending application discloses means for folding a shirt whereby the folding operation begins substantially simultaneously from two opposed locations, usually near the sleeve ends or cuffs. The operation then progresses inwardly so as to carry progressively folded portions inwardly therewith, and fold such portions along fold lines established by such hinged members. The operation of the novel means herein to be disclosed is associated with the same general scheme, and will be described in detail below.

In the operation of the 'device shown and described in my aforesaid copending application there was an occasional tendency to crush or wrinkle one or both shirt cuffs since the method of folding necessarily placed the cuffs within the folded shirt.

An object of the present invention is to provide means for maintaining one or both cuffs in such' position that they are not crushed or wrinkled during successive folding operations. 7

Other objects and advantages will be apparent from a study of the following specification, in conjunction with the accompanying drawings, showing several embodiments of my invention, in which:

The general operation of s'hirt folding, as performed on folding apparatus such'as thatshown in the accom- 4. At a convenient point in panying drawings, is fully described in my aforesaid United States Letters Patent Number 2,665,039, and Will be reviewed herein only to the extent needed for a thorough understanding of the present invention, namely the elements adapted for the maintenance of the shirt cuffs in protected position.

From the operators working position, at the front of the machine, there can be seen two folding arms 20 and 21 (Figs. 1 and 2) swingable upwardly and then converging inwardly on respective axes of rotation consisting of shafts 22 and 23. The arms are pinned to said shafts and also pinned to said respectiveshafts are driven gears 24 and 25. The operators position also overlooks-two folding wings 26 and 27 swingable upwardly and inwardly on respective axes constituting hinge pins or shafts 30 and 31 to which the said folding wings are pinned. Driven gears 32 and 33 are pinned to shafts 30 and 31. The operator lays the shirt 34 on the apparatus, button strip down, central plate 35 and beneath folding wings 26 and 27, but with the shirt sleeves 34a and 3411 respectively across the swingable portions of arms 26 and 211. It will be understood that by means soon to be described, arm 21 is first swung upwardly and inwardly to the position of Fig. 3, carrying shirt sleeve 34]) along with it, and immediately thereafter arm 29 is swung upwardly and inwardly carrying shirt sleeve 34a with it across sleeve 34b. Wing 27 is then swung upwardly and inwardly carrying an enfolded shirt body portion and an upper sleeve portion of sleeve 34b, after which wing 26 is swung upwardly and inwardly, also carrying an enfolded shirt body portion and an upper sleeve portion of the sleeve 34a so as to achieve the effect illustrated in Fig.

tail is usually folded upwardly and inwardly but this step is not shown or described herein since it is not necessary for an understanding of the present invention. A tape or other attaching means may be wrapped around the folded assembly shown in Fig. 4, and the folded shirt slid off the arms and wings, after which said arms and wings are returned to the Fig. 1 position, ready for the next operation.

Folding wings 27 and 26 swing on axes consisting of shafts 30 and 31. These shafts are carried on a Wing bracket 36 which in turn is rotatable on a transverse shaft 39. A main bracket, herein termed for convenience the arm bracket 4th, carries folding arms 20 and 21, and is also tiltable around shaft 39 by means of a pair of spaced arms 4th: which have bearing portions 40b.

Swinging movement of the arms and wings is effected in the following manner. The driven gears 24 and 25 for arms 2i and 21 engage driving sectors 43 and 44, and the driven gears 32 and 33 forwings 26 and 27 engage driving sectors 45 and 46. Driving sectors 43 and 44 are journalled on arm bracket to. Driving sectors 45 and 46 are journalled'on depending extensions 41 and 42 of the wing support bracket 36. A carriage 47 is vertically movable on arm bracket 4%). A double acting fluid power motor 43 is mounted on bracket 40, and its piston rod 49 is linked to the carriage so that admission of fluid power to the bottom or top of the cylinder respectively ralses or lowers carriage 47.

Carriage 47 carries four rollers respectively numbered 50, 51, 52 and 53, the purpose of each roller being to operatively contact a respective cam track 44a, 43a, 46a, and 45a in the driving sectors 44, 43, 46 and 45 when the carriage is moved, so as to rotate said sectors. The sectors are contacted and rotated sequentially so as to produce successive folding movements of the arms and Patented Dec. 20, 1955.

with its body beneath the the folding sequence the,

position of the wings during arm folding operation, and thereafter fixing the position of the arms during wing folding operation.

The first such means consists of plates 56 and 57 (Fig. 2) one secured on each side ofthe carriage 47. 'The outside edge of each plate moves in sliding contact with respective pins 59, 68 on gear sectors 46 and 45, thereby preventing the said gear sectors and wings 27 and 26 from moving until the arms are fully folded, at which time the plates 56 and 57 have moved upwardly with the carriage to clear the pins and permit movement of the gear sectors 46 and 45.

' A second such interlock consists of a flattened side 33a, on wing gear 33 cooperating with a short extension 46b on gear sector 46. When the wing 27 is folded over, extension 4611 lies against the fiat side 33:: of gear 33, and roller 52 moves along side of extension 46b, thus holding wing 27 in folded flat position while the other side of the shirt is being folded.

A third such interlock consists of plates 63 and 64, secured to carriage 47 and having outwardly facing flat surfaces which move behind small rollers 65 and 66 on sectors 44 and 43 so as to hold the arms 21 and 21 positively folded while the wings are being folded.

As previously noted, the wing bracket 36 swings around shaft 39 from an outward, wings-down position to an inward, wings-up position. I have provided a biasing device for maintaining this bracket in one or other of said opposed positions by means of an over-center spring device 67 on a link rod 68, the spring being partially compressed between blocks 69 and 70, block 69 being fixed to wing bracket 36, and block 70 being carried on machine frame member 71.

Proceeding specifically to the subject matter of the present invention which operates in cooperation with the folding mechanism hereinabove described, I have pro.- vided means for assuring a positive hold-down action effective on the right hand cuff 74, one embodiment of such means being shown in Figs. 3 to 8. In my aforesaid United States Letters Patent Number 2,665,039, the moving arms and 21 were adapted to cooperate in flipping back cuff 74 upon its sleeve 34b as indicated in' the interim position shown in Fig. 8 wherein arm 21 is near-.

ing the inward end of its folding position and arm 20 is swinging clockwise to come down over arm 21, striking the cuff 74 to achieve the result noted above. The purpose of course was to have the open end of the cuff face away from the oppositely moving fold executed by arm 20, and thereby avoid crushing or wrinkling the cuff, which, particularly when starched, tended to stand open. This arrangement was usually quite helpful but in certain cases, usually involving shorter sleeves, arm 21 terminated just behind the point of attachment of the cuff 74, and said cuff tended to remain open positively enough so that it was not flattened down in hoped-for manner by the subsequent descent thereupon by the opposite sleeve 34:: (Fig. 3). mediately thereafter had a tendency to crush cuff 74.

I have accordingly provided positive means to hold down cuff 74 consisting of a supplemental clamp arm 75, Figs. 1, 6 and 8. mounted on wing hinge pin 31, and it has an upwardly extending finger '77. Collar 76 is held in place by a washer 78 and a screw 79 tapped into hinge pin 31. Collar 76 has a pair of protruding abutment pins 80 engageable by an upwardly biased crosspiece 81 of a T-shaped member which has tubular leg 82 telescoped on a pin 83 extending upwardly from bracket 84 (Fig. 6). A spring 85 normally tends to hold cross piece 81 against pins 8'!) whereby to maintain clamp arm 75 in its uppermost or idle position. Cross piece 81 is secured on top of a tubular guide member 82 which is slidable on pin portion 83 and has a cut out section at the front straddling the narrow section of bracket 84 to prevent turning of cross piece 81.

Wing 27 coming in im- It is secured to a collar 76 freely.

Arm 75 may be manually swung 90 to the left or right, in which position the contacting pins will be m straight line relation to the center line of the pivot, and of pressure member 81-82, and the arm will remain 1n such position until dislodged therefrom manually or otherwise.

Referring again to Fig. 8, the right hand sleeve 34b is being folded just in advance of the left hand sleeve 34a, and the cuff 74 is being flipped backward, to the right, after momentary contact with folding arm 20. This latter arm 20 has just engaged clamp arm extension 77, thereby swinging clamp arm 75 clockwise so that it will flatten and smoothly hold down cuff 74. Thereafter wing 27 swings over and inwardly, followed by wing 26. It will be seen from Fig. 3 that folding arm 21 lies beneath clamp arm 75. Therefore, when the folded shirt has been removed, and the folding members open out, folding arm 21 in its movement flips clamp arm 75 to its original upward, idle position.

Clamp arm 75 has another function when a shirt with French cuffs is being folded, in which function a second clamp arm 88, to be described hereinafter, participates. Fig. 5 shows the manner in which shirts having French cuffs are initially disposed for folding. For such shirts the sleeves are first manually disposed as shown, after which the folding operation proceeds in the usual way except that since the sleeves do not initially overhang folding arms 20 and 21, said arms move in as idlers just ahead of the wings 26' and 27. If there were no holding means for the sleeves. in the Fig. 5 position, then they would be dis-arranged when the wings swing in. In my aforesaid United States Letters Patent Number 2,665,039, I provide studs 89 and 90- (Fig. 1) secured to the table top and extending up through holes in the folding wings, upon which the cuff link holes were affixcd to hold the cuffs until pulled from said studs by folding-over motion of the wings. This works fairly Well, but since nothing. holds the cuffs after the wings moved a relatively short distance the cuffs and sleeves, sometimes became displaced, and mussed or inaccurately, folded. I have therefore developed the present arrangement to maintain the cuffs in position during a complete folding swing of the wings, although I' retain the studs 89 and- 90 since they serve in initially aligning the cuff sections.

The use of clamp arm 75 in this connection is obvious, since the operator merely swings it down manually to the Fig. 5 position, where it is held by the straight line, slightly over center relationship previously described.

For the other side, I have provided the previously mentioned-clamp arm 88,- In normal, idle position it is vertical (Figs. 1 and 7 Clamp arm 88'is secured'to a collar 91 which is freely rotatable on the hinge pin 30' for wing 27, being positionedin a gap adjacent the wing bushing. As best seen in Fig. 1 the collar 91 is cut back fiat to slightly beyond-the 'axial center for about the rear half of its length. Hinge pin 30,has a pin 92 to act as an abutment or stop to-th e flat side of collar, and as will appear, the pin returns-arm 8,8'during unfolding. Likewise the front lower portion of collar 91 has a small depression in its inner periphery to form aball detent in cooperation with a ball and spring arrangement 93, Fig. 7. The depression is so positioned as to normally maintain arm 88 in vertical position.

Hinge pin 3 0-issecured' to wing 27 and turns therewith. When clarnp arm 88 is manually swungclockwise over on the cuff to hold it, pin 92. remains vertical. However, when wing 27"fold s inwardlyclamparm 88 necessarily moves with it, and when the wing, and its hinge pin complete the-inward swing, pin 92 hasswung ,180? and is vertically down. When .the folded shirt is removed, and wing 27 swingsoutwardly, pin 9 2,after-a 90f portion of the swing contacts the flat face of collar 91 and in the next 90? increment of hinge movement the pin: returns clamp arm 88 to its original. vertical position.

When used with French cuffs, the extension 77 of arm '5 75 bears a different relationship to the folding elements. As hereinabove described, when a shirt with plain cuffs is being folded, extension 77 is contacted by folding arm 20 (Fig. 8) and lies thereunder, clamp arm 75 overlying folding arm 21. Thus, on unfolding, arm 21 flips arm 75 upwardly to idle position.

With French cufi shirts, folding arm 20. folds over above folding arm 21 but misses extension 77 because the extension is fiat above wing 26 (Fig. Then wing 27 folds over followed by wing 26, thelatter moving clamp arm 75 and extension 77 with it, to a position above wing 27. Then, in unfolding, wing 26 opens first followed by wing 27 which, underlying clamp arm 75, flips the latter up. Now folding arm opens, and, being on the right side of extension 77, it contacts this member and moves it part way over to the left before the arcuate path of the members diverge enough for folding arm 20 to clear the end of extension 77. Clamp arm 75 then snaps back to its spring-urged vertical position. I

In another embodiment of my invention, illustrated in Figs. 9 to 12, I show a emf-positioning device which is quieter in operation while being positively driven, rather than, as in the prior embodiment, operated by-physical contact with the basic folding elements during their folding movement. Also, whereas in the previosuly described embodiment the arrangement precluded adjustment or change in the relative positions of the parts involved as they proceed through the folding sequence, the embodiment now to be described provides flexibility in this respect.

This modified arrangement separates the ordinary cuff flattener from the French cuff holding function. The latter is accomplished by a separate small arm similar in action to the one used on the right side, as seen at 38 in Fig. 1. As noted hereinabove in the description of the first embodiment, the member 75 when flipped over on a French cuff had its extension 77 on top of arm 20, and in the unfolding procedure extension 77 had to be swung back beyond its normal vertical position before it cleared arm 20. The actuating means for the present em-. bodiment is not adapted for two-positional operation (French cuff and ordinary cuff) so the French cuff holder will be described in its sole function in this embodiment.

As in the previously described arrangement, the flattening member is pivoted around the axis 31 of the left folding wing 26. It is made up of two rods 95 and 95a welded, brazed or otherwise attached to each other, the lower piece 95 being straight, and extending back (right in Fig. 12) beyond the upper piece 950. While I have found this arrangement to be quite convenient, it will be obvious as the description proceeds that other constructions might be substituted. However, spaced rods are better able to contact and smooth cuffs of varying widths.

A first support and bearing for the flattener is provided by an arm 96 which has a collar or bearing portion 96a at its lower end, freely rotatable on the hinge pin 31, and located in a cut out portion of the bracket which carries wing 26. A second support for the flattener is provided at the rear end, which is fitted into a bore in an arcuate member 97 adjustably secured by screws 98 in a plate member 99. Plate 99 has a circular opening fitting freely on a rear hub portion of the wing pinion 32 and is retained by an end disk 100 which is fastened to the rear face of the hub by screws 101. Thus the cuff flattener is supported at two separated points by the axis of the wing hinge. As best seen in Fig. 10 it is normally held in retracted position by a small tension spring 104 held at one end by a pin 105 on the carrier plate 99 and at the other end on a bracket 106 on the wing support casting. Adjustable stop means is provided in the form of an adjustable length stop stud 107 which determines the angular position of the flattener member when idle.

Means is provided for swinging the flattener to operating position. This consists of a cam face 57:; on the movable plate 57 in cooperation with a cam-following B roller 108 on plate 99. The plate 57, aspreviou'sly' tiescribed, basically serves as a means which, by its movement insures correct sequential folding movement of the wings and arms. In the present instance this plate has been somewhat lengthened, and its top surface modified to provide the cam face 57a. As will be recalled, the

plate 57 is carried on the operating slide 47, which also carries a number of rollers for sequentially operating the driving segments 43, 44, 45 and 46. These rollers are so located with respect to each other, and to the cam face 57a that the operation proceeds in the following sequence.

When the operating slide 47 is in its lowermost position, the cam face 57a is in the position shown in Fig. 10. As the slide moves upward, arm 21 is first swung to the folded position of Fig. 11, so that cuff 74 is thrown inwardly and upwardly adjacent the flattening portions and 95a. At this point arm 20 is passing the vertical position, as indicated in full line in Fig. 11, and cam face 57a is just approaching contact with roller 108. Arm 20 continues to move clockwise and cam 57a contacts roller and swings the flattener member down on the cuff. The sequence is such, cam 57a being disposed to be quick acting, that the fiattener member reaches the final horizontal position slightly before arm 20, as indicated by broken line in Fig. 11. About this time the roller 108 rides over the corner 57b of plate 57 so that thereafter the side edge of plate 57 maintains the flattener in its downward or active position during the balance of the folding sequence while continued upward movement of slide 47 causes folding motion of the wings 26 and 27.

The French cuff holder in this arrangement is substantially the same as the one described with respect to the first embodiment of my invention and previously identified by reference character 88, except that in this second embodiment two abutting pins are used instead of the former pin and cutout face.

A finger 110 has a collar ill freely mounted on the hinge. pin 31, Fig. 12. A depression or detent in the lower portion of the collar cooperates with a complementary member 112, in this instance a spring pressed ball on the wing bracket to normally hold the finger 110 in the Fig. 10 position. When a shirt with a French cuff is laid out and the cuff folded as in Fig. 5, the finger 110 is manually flipped over on it, the abutment pin 114 on collar 111 swinging away from a stop pin 115 on the wing journal. When wing 26 folds inwardly it car ries finger 110 with it. Upon unfolding movement of the wing 26, the wing moves away from finger 110, but during continued movement of the wing journal the pin 115 strikes pin 114, returning finger 110 to its idle position, as shown in Figs. 9 and 12.
